So I started ntp. That’s when I noticed it was not being started by /etc/rc.conf. But I thought not much more of it. Later, I thought: let’s add that to my Nagios configuration. First stop: check nrpe2.cfg and see if there’s an entry for check_ntp. There was. Oh… well, let’s check Nagios. Oh, ntpd is already monitored. OK, what’s going on here?
